Citizen science

Turn every dive into ocean science

The ocean covers 70% of the planet but is the least-recorded place on Earth. Scientists can't be on every reef. Divers are.

  1. You log itWhat you saw, from your dive computer file or by hand.
  2. We check itPinned to the dive site and matched to a scientific name.
  3. Scientists can use itKept with its date, depth and place, in the format the big open species databases like GBIF use.

What scientists need, and how you help

  • More places

    Most ocean records come from a few coasts. Log every dive, even quiet sites.

  • What wasn't there

    Full dive logs show when a species goes missing. Log every animal, not just the highlights.

  • Same reefs, every year

    Change only shows up over years. Keep logging your home reef.

  • Names they can trust

    Lookalike species trip up records. Tag animals and add a photo.
